The AIPER Scuba V3 is a revolutionary cordless robotic pool cleaner that leverages artificial intelligence to transform pool maintenance. It is designed for homeowners who want a truly hands-off experience, from scheduling to retrieval. The robot uses a single front-facing AI camera to detect over 20 types of debris and navigate directly to them, cleaning up to 10 times faster than traditional pool cleaners.
Standout features include the Cognitive AI Navium Mode, which creates autonomous weekly cleaning plans based on pool size, weather, and cleaning history. Once activated, the robot runs without any user intervention, keeping your pool consistently clean and swim-ready. The automatic return to the waterline after cleaning, coupled with real-time app notifications, eliminates the need to enter the pool or use tools for retrieval.
Design and build quality are impressive. The Scuba V3 weighs only 8.2 kilograms, making it easy to lift and transport. The wireless charging dock requires no installation and safely charges the robot without plugs or drying. The MicroMesh Multi Layer Filtration System captures both large debris (180 micron) and ultra fine particles (3 micron), ensuring crystal clear water. Additionally, the device is TUV certified for data privacy, processing all visual information on the device without storage or uploads.
Drawbacks include a higher price point that may not suit all budgets. The reliance on the AI and app means that connectivity issues could disrupt the automated scheduling.

Buying Guide
Cleaning Performance and Coverage
For large pools, the cleaner must cover every corner efficiently. Look for models with smart navigation, wall climbing, and powerful suction. The Dolphin Nautilus CC Plus uses active scrubbing brushes and climbs walls to scrub tile and surfaces, while the AIPER Scuba V3 employs an AI Patrol System that detects debris and navigates directly to it, cleaning up to ten times faster than traditional methods. Both ensure thorough cleaning without missing spots.
Filtration System
A high-quality filter traps fine particles and keeps water clear. The Dolphin features a top-load filter basket for easy debris removal. The AIPER uses a MicroMesh Multi Layer Filtration System with a 180 micron layer plus an ultra fine 3 micron layer, capturing sand and invisible contaminants. This is especially important for large pools where debris accumulates quickly.
Ease of Use and Maintenance
No one wants a complicated setup or heavy lifting. The Dolphin offers plug-and-play simplicity: just plug in, drop into the pool, and it runs for two hours. The AIPER is cordless and featherlight at 8.2 kg, with a wireless charging dock and automatic return to the waterline after cleaning. Its app sends notifications, so you never need to wade in to retrieve it.

Frequently Asked Questions
How long does a robotic pool cleaner last for a large pool?
With proper care, most high-quality robotic cleaners last 3 to 5 years. The Dolphin Nautilus CC Plus and AIPER Scuba V3 are built with durable components and backed by solid warranties, ensuring long-term performance even with frequent use.
Can a robot pool cleaner handle leaves and large debris?
Yes, both models are designed for large debris. The Dolphin uses active scrubbing brushes to loosen and capture leaves, while the AIPER’s AI camera identifies and navigates to debris types. For heavy leaf loads, consider pairing with a leaf skimmer. See our guide on best above ground pool robot for leaves for more options.
Do I need to install a separate pump or filter for a robotic cleaner?
No, robotic pool cleaners are self-contained units. They have their own filtration system and motor, so they work independently of your pool’s pump and filter. Simply plug them in (or use the wireless charging dock for the AIPER) and let them clean.
Which is better for a large in-ground pool: corded or cordless?
It depends on your pool size and layout. Corded models like the Dolphin offer unlimited runtime and consistent power, ideal for very large pools. Cordless models like the AIPER provide freedom from cables and easier handling, with battery life sufficient for most residential pools. Both are excellent choices for large pools.
